Carbon And Nitrogen As Regulators Of Algal Growth In Treated Sewage, Edward G. Foree, Charles Reece Scroggin

KWRRI Research Reports

Continuous flow algal cultures were grown under three different growth conditions using secondary sewage treatment plant effluent as the growth medium. The only variable within each run was the hydraulic residence time. The concentrations of growth regulating nutrients were varied between the runs so comparisons of the algal mass, composition, nutrient uptake, and genera could be made. The importance of CO₂ availability for algal growth was also studied. A kinetic theory which based algal growth on cellular nutrient concentration was verified. The second phase of the study was a batch culture study in which the same growth medium was …

Opening Remarks - Fifth Vertebrate Pest Conference, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 5th (1972)

It is a pleasure to welcome you to the Fifth Vertebrate Pest Conference. It has been 10 years since the first Conference was held in Sacramento in February of 1962. The attendance has grown at each successive conference and, from the looks of the audience this morning, we shall surpass all previous records. It would, however, be wrong to judge the significance of this conference on attendance alone, for we are equally or more concerned with the quality of the conference and its ultimate contribution to the specialized area of wildlife management. The Conference is sponsored by the California Vertebrate …

Keynote Address - Vertebrates: A Resource Needing Management, Donald A. Spencer

Vertebrate Pest Conference Proceedings: 5th (1972)

A veritable storm of concern for wildlife - approaching biotechnology - is currently sweeping the nation. Some of this concern has a sound basis. But the very best of ideas and programs can be carried so far that they become irrational. We appear to be driving head-on into irrational actions with respect to environmental good housekeeping. The vegetative cover in the United States has changed markedly as the result of Man's occupancy, reducing the habitat on which some wildlife species depend and greatly enhancing that of others. Competition, a no-holds-barred struggle, continues unabated between all living things for the finite …

The Extending Of Cotton Rat Range In California - Their Life History And Control, Dell O. Clark

Vertebrate Pest Conference Proceedings: 5th (1972)

Cotton Rats (Sigmodon hispidus eremicus Mearns) are known to have reached the Imperial Valley in 1921 from the Colorado River along canal banks. Recently (1967-69) cotton rats were found distributed throughout the irrigated portion of the Imperial Valley, Imperial County, California. Limited crop damage has occurred and is described. Life history information is included. Control measures are listed.

Related Laws On Exotic And Native Wild Animals, Donald F. Stork

Vertebrate Pest Conference Proceedings: 5th (1972)

This paper is submitted in an effort to acquaint the personnel of allied State agencies with related laws which control the public and private possession of live exotic and native wild animals. The need for this common knowledge of related laws by agencies with law enforcement responsibility is readily apparent when the annual number and related problems from imported or resident wild animals in California are examined. In addition to resident wild animal populations, millions of fish and thousands of mammals, birds, and reptiles enter California each year through the utilization of most methods of transportation. Most of these imported …

Obstacles To Economic Progress In Ethiopia's Red Sea Coast And Gulf Of Aden, Abraham Alemayehu

Marine Affairs Theses and Major Papers

Ethiopia is a coastal state whose overall economic progress has been and still is being affected by a number of coastal and related obstacles. This paper will attempt to discuss each and every one of these obstacles and other relevant aspects in order to justify as much as possible Ethiopia's lack of progress in economic development. By no means these are not the only obstacles responsible for affecting the country's entire economic progress. The obstacles that I would like to present here are only those which are more or less directly related to maritime, geographical and geopolitical problems on the …

Fisheries Report No 11 - The Fauna, Flora And Planned Usage Of The Dampier Archipelago, A. A. Burbidge, R. I. T. Prince

Fisheries Research Reports

The Dampier Archipelago is a group of islands off the north west coast of Australia (20 20! - 20 45'S, 116 Cast . 117°E), first discovered by William Dampier in 1699 and subsequently named after him by the Baudin expedition of 1801. This name has since been applied by some authors to include all islands from Roebourne to North West Cape, including both Barrow Island and the Monte Bello Islands, but it is more correctly applied to those islands within a 30 mile radius of the town of Dampier.

Ir. recent times, three parties have visited the Archipelago and examined …

Fisheries Report No. 10 - An Investigation Into The Status Of Introduced Trout (Salmo Spp.) In Western Australia, Dr N. M. Morrissy

Fisheries Research Reports

Both brown (Salmo trutta L.) and rainbow (S. gairdnerii trout Richardson) have been introduced into inland waters of the south-west of Western Australia to provide an amateur sport fishery on a gamefish. The large indigenous marron (Cherax tenuimanus Smith) is present in most of these waters. The only large native fish present is the cobbler (Tand- anus bostocki Whitley) which, while highly edible like the marron, has no game-fish qualities.

Hatchery production of trout for stocking waters has been centred at Pemberton in the lower south-west since 1931 when Mr. Cyril Glew, acting in a private capacity, succeeded in hatching …

Water Resources Of Part Of Canyonlands National Park, Southeastern Utah, C. T. Sumsion, E. L. Bolke

Canyonlands Research Bibliography

Canyonlands National Park is in about the center of the Canyon Lands section of the Colorado Plateaus physiographic province in southeastern Utah. The part of the park discussed embraces an area of about 400 square miles comprising isolated mesas, precipitous canyons, and dissected broad benches near the confluence of the Green and Colorado Rivers, the only perennial streams in the area. The climate is arid to semiarid; normal annual precipitation ranges from less than 8 to about 10 inches. Potential evapotranspiration is about 41 inches annually.

Geology of the park is characterized by nearly horizontal strata that dip gently northward. …

Agriculture And Pollution In Western Australia. Part 1. Background, C V. Malcolm

Journal of the Department of Agriculture, Western Australia, Series 4

For centuries there has been awareness of pollution but it has received dramatic publicity in recent years.

In Western Australia, provisions for its control are written into the Health Act and many other Acts besides the Environmental Protection Act of 1971.

A number of factors have acted worldwide and locally to increase awareness and concern about pollution, and to justify careful examination of the problems it causes.
